3 Rough Processing Drastically Shortened Time The reamer and head can be clamped simultaneously with one-touch operation (While maintaining high rigidity). Finish Processing Simple control reduces the required setup time. Important! Be sure to mount the reamer and head before clamping. If connection is performed while either of them is not mounted, the joining surface of the clamp may be deformed and breakage may occur. This is the strength of the hydro chuck! Simultaneous clamp connection of the inner and outer diameters while maintaining high rigidity allows high accuracy, making reamer run-out adjustment virtually unnecessary. (mm) Oil Chamber 60 (L/D=10) ø Reamer run-out of 5μm or less is ensured. (When the master reamer and master head are mounted.) 2

The reamer adjustment screw is an accessory (1 piece), which can also be additionally purchased as a stand-alone item. A hexagon socket set screw (M4) is included with the tool holder. It should be used as a stopper when discharging coolant with the use of an external oil supply. 3 a : Inventory maintained in Japan.
